Why are there (at least to my knowledge) no rotatable sensors instead of grips for portrait photography. It seems like a great solution to obtain a lightweight DSLR for both landscape and portrait photography. Are there technical difficulties?
The reasons for not having a rotating sensor that I can think of are:
- Technical difficulties
- No demand of it since portrait photographers want a bigger camera anyway since most sessions are in studio and weight is not an issue.
- The camera would be more fragile having the rotating construction.
On the other hand I see secondary advantages having a rotating sensor such as automatic horizontal leveling and even image stabilisation from roll movement.
Is there something I’m just missing here?
